Recently I moved a shop to a new server and domain. Everything is looking good so far. When I change something inside a product and press 'save' I get a fatal error:
Fatal error: Call to a member function beginTransaction() on a non-object in /public_html/app/code/core/Mage/Core/Model/Abstract.php on line 313
When I navigate back to the product editing the changes are saved. Does anyone know how to fix this?
